Set your command line parameter --max-mem-size=1G and don't open extraneous programs.

You should easily be able to handle this many 133A chips with 1Gb. Otherwise use justRMA in the devel version of affy.

I am trying to read 35 affy 133 A chips using the RMA function and despite 
that with the same computer I was able to read 38 A chips few days ago, today 
it cannot process 35 chips ...?

> data<-ReadAffy()
Error: cannot allocate vector of size 69308 Kb  

I m with a PC, win XP, 1Go RAM, Athlon 1900+, 3 Go free on the HDD

I restarted my PC and trie again but no change.

Any idea ?
